To '(ZZ cdrom it may' concern.'

Be it 'known that l, JOHN 'YINGLING, a citizen .of the United: States, residing .at

Topeka, in the countyfoi Shawnee ,andv

Stateo'i' Kansas, have invented certain new and `useful lmproven'ients in, `,H 'eadlight Lamps; and l do decla'refthefollow-ing ,to `be a lfull, clear, and exact description of the invention, 4such `as will enahleothers skilled' inthe artto which `it v rp'pertains-to make and use the same, reier'ence being had to the' iorrmotor vehicles'y and motor boats andthe like andthe primary;objectiefthe invention is to provide an improved deecting inech-v`r a'nism for d'ellectingjth'erays of light'below` the vision of pedesi'n'iansV 'and "below lthe drivers ofilv `onfcoming,vehicles so the danger of blinding the pedestrians'- or drivers of oncoming vehicles by the glare of the lamps will be eliminated.

Prior to my invention, many devices have been provided for delecting the rays of the lamp toward the ground and to preventthe light rays spilling in an upward direction, for example, prior to my invention hoods have been provided, either adjustable 0r fixed, arranged at the upper portion of the lamp, but in so far as I am aware, none of these deflecting mechanisms included means at the upper portion of the lamp for shutting oli the light and shutters at the lower portion of the lamp for rendering the lower portion of the reflector ineffective so the hooded constructions were objectionable because they did not completely solve the problem, due to the fact that the light rays relected from the lower portion of the reflector were drawn out and above the outer edge of the reflector hood at the upper portion of the lamp. Y y

My invention eliminates the objections heretofore encountered and it consists in certain novel parts and combination oli' parts, all of which will be specilically described hereinafter, reference being had to the accompanying drawings, in which- Fig. 1 is a longitudinal,'sectional View through a lamp constructed in accordance with my invention.

4The lia-mp i1 .is provided 1- with a f reflector 2 of usual construction and there is laalight source consisting of `a bulb 3A appropriately located in the lamp. The rim lleisprovided` with a .I segmentalf slot `5 to receive pivoted shutters 6,57 andLSf-.whichconstituteareflect- 'inghoedmot-nited uponthel pivot bolts 9.and 10. The innermost segment :has a dependjingwlalngel12 which closes-the :front offthe` slofI 5! when the vhood is extended. asfsh'ownin Fig. 1.'- Thepivot 9 .carries:anactuating..

sleeve 13 having stepped recesses 14. and 15. TheA stepped recess: :l5 is,.provided1 with .slots of-diierent ,arc Y:lengths i to progressively.

engagel the. .ledges otsh'ntters 116,117A `and 1:8 mounted. onfthepivotand--adapted to '..be moved over the bottom portion 19 `of the delector 2 as shown in Fig. 1, at the same time that the hood is extended.

The recessed portion 14 is slotted in substantially the same manner as the portionl 15 so that the segments 6, 7 and 8 are pr gressively picked up to extend them forward as shown in Fig. 1. The segment 16 is received in an end recess 20, in the end of the actuator 13, see Fig. 3, so that it moves with the actuating sleeve 13. The segments 17 and 18 however are picked up one after the other to extend them over the reflector and shut oli the reflecting surface so' that the rays of light from the light source 3 will not be directed upward. The segments are normally urged in either collapsed position or in extended position by a spring 21 which is anchored at 22 to the casing l and which is fastened on the disk or head 23 at 24. The disk or head 23 is in the formk of a pulley with a groove 25 around which a cable 26 passes, the cable being operated from the front oi the car or -from a convenient point on the motor boat. When the spring connection 24 swings to one side of the vertical axis or to one side of dead center position in one direction, the shutters will be closed and when it swings to the other side of dead center position, the

yshutters will be extended. This will be clearly apparent by reference to Fig. 5. Any Well known mechanismmay be used for operating the cable 26.

Since the angle of reflection is equal to the angle of incidence, it will be apparent that when the deflectors are in the position shown in Fig. 1, the light rays will be directed downward only and no light rays can be directed in an upward and outward direction. It will also be apparent that when the deflectors are not in use the hood members will be received in the recess 5 While the bottom deflecting segments will be collapsed at the front of the lamp. When in this position the lamp will function as an ordinary lamp, but whenever it is desired to throw the lamp rays downward the actuator will be swung to cause the members 6, and 8, 16, 17 and 18 to more or less approximate the arrangement shown in Fig. 1. l

hat I claim and desire to secure by Letters Patent is:

1. A head light lamp comprising a casing, a reflector and a light source, in combination with a movable hood-consisting of a plurality of hinged segments at the upper portion of the lamp and a movable reflector covering means consisting ofV a plurality of hinged segments at the lower part of the reflector. 1 Y Y 2. A head light lamp comprising a casing, a reflector and a light source, an eXtensible and contractable hood receivable in a groove in the casing and an extensible and contractable covering means for the lower part of the reflector.

3. A head light lamp comprising a casing, a reflector and alight source, an extensible and contractable hood receivable in a groove in the casing and an extensible and contractable covering inea-ns Jfor thel lower part of the reflector, and means for simultaneously actuating the hood and the covering means.

4. A head light lamp comprising a casing, a reflector and a light source, vin combination with a plurality oiff semi-circular hood forming elements and a plurality of semi-circular reflector covering elements, the two sets of elements co-operating'to close oli the lower 1 porti-on of the reflector and direct the light rays downwardly.

5. A head light lamp comprising a casing,V

a reflector and a light source, .a hood comprising a plurality of segments pivotally secured to the casing, a reflector covering means comprising a plurality of pivoted segments and a shouldered actuator carried` by the casing, and adapted to successively move the segments of the hood and the covering means and means Vfor opposing the movements of the segments by the actuator. ln testimony whereof I afliX my signature.
